This invention relates to a roof construcis which will hold not only theroof flashing but also a counter-flashing.

Another object is to provide a flashing block formed in a sin le piecewhich can be set up readily for engagement with both the ,3 flashingandthe counter-flashing.

A further object is to combine with the flashing block a means forretaining asphalt or any other suitable binder used for causing theflashing to adhere to the block.

in A still further object is to provide a flashing block so constructedas to permit insertion of a built-up roof without necessitating anabrupt bend of the roof surface.

With the foregoing and other objects in 2;) view which will appear asthe description proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention 7 herein disclosed may be made within thescope of what is claimed without departing from the spirit of theinvention.

In the accompanying drawing, which is a sectionthrough the flashingblock and a portion of the roofing and adjacent structure, the preferredform of the invention has been v shown.

Referring to the drawing by characters of reference, 1 designates aflashing block formed in a single piece of concrete or other Cirsuitable material and this block has an upper groove 2 extendinglongitudinally within one face thereof below which is arranged anotherlongitudinal groove 3 preferably deeper and wider than the groove 2 anddisposed at an acute angle to the adjacent face of the block. The blockhas itsbottom portion extended outwardly beyond the grooved 550 face ofthe block to provide an inclined surface & which constitutes acontinuationv of the bottom of the slot 3. This surface is corrugatedlongitudinally of the block'as indicated at 5 to provide longitudinalrecesses or gutters in the extension 6 of the block 1.

In practice the blocks 1 are set up in their proper positions, eachblock being placed in one operation so that the laying of the blocks isgreatly simplified as comparedwith those requiring the employment of twoor more pieces to each complete flashin block. Afterthe blocks have beenset up and alined pitch, tar, or other suitable binding material indicated at 7 is placed in the recesses or gutters 5 so as to form acoating for the inclined surface of the block; this coating materialbeing extended upwardly into the groove 3. The marginal portion of abuilt-up roof indicated at R can then be inserted into the groove 3 andaflixed to the inclined surface 57 of eirztension 6 by means of thecoating material After the built-up roof has been placed in position thecounter-flashing, indicated at 1115 inserted into the groove 2 andapplied to that portion of the built-up roofing supported by theextension 6. Any spaces left in the grooves after the several parts havebeen assembled can be filled with roofing cement or other suitablematerial indicated generally at C. o

By providing the corrugated surface the coating or binding material willbe prevented from flowing downwardly to an objectionable extent if of anature tending to flow when subjected to heat. The corrugations alsoserve as an added means for preventing moisture from working upwardlyalong the extension 6 of the flashing block.

What is claimed is:

1. A flashing block formed in a single piece of material havingvt-hebottom portion thereof extended well beyond one face of the block toprovide an inclined surface for supporting the inclined marginal portionof a roofing material, there being a longitudinal groove extending intothe block from said surface and having its bottom alining with a andconstitutinga continuation of said inclined surface for supporting theedge of e.

said marginal portion, there being a series of transverse grooves in theinclined surface of the extension and in the alining Wall of the groovein the block for retaining an adhesive applied to said surface and Wall.

2. The combination with a flashing block formed in a single piece ofmaterial having an extension at the lower portion thereof projectingWell beyond one face and superposed grooves in said face of the block,the bottom wall of one of the'grooves constituting a continuation of onesurface of the extension, there being longitudinal corrugations formedby said surface and disposed in an inclined Series, of a roofingmaterial extending into one of the grooves, means retained by thecorrugations for afiixing a portion of said material to theextension,omeans. for filling the groove above the roofing materialtherein to hold the afiixingv means against a release from thecorrugationsin said grooves,

and a counter-flashing seated ,in the other groove and bearing upon thatportion of the roofing arranged on the extension.

In testimony that I claim the foregoing as my own, I have hereto afiixedmy signature.

PAUL SCHONERT.
